Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. You might also notice the soil stays damp for more than a week.
What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient deficiency
PossibleHow to tell: The older leaves turn yellow while the veins remain green. This often happens if the plant has been in the same pot for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength once every 4 to 6 weeks during the growing season. If the plant is root bound, consider repotting it into fresh soil.

When to worry
Worry if the yellowing spreads rapidly across the whole plant. It is normal for the very bottom leaves to yellow and drop as the plant matures.
Stopping it coming back
Stick to a consistent watering schedule and only water when the top inch of soil is dry.
